The equipment disclosed by the utility model is fast in pulling, and can simultaneously carry out operations of sand bailing, pipe scraping and drifting, fast carry out workover operation, reduce the operation procedures, save the operation cost, reduce the labor intensity of workers and achieve outstanding economic benefit.
Description
Technical field
The utility model is the assorted column jacket that the oil-water well workover treatment is used, and is a kind of quick well workover pipe string.
Background technology
Sand in the oil-water well stratum can be carried out by liquid stream, and what have can flow to and reach ground with liquid, and some meetings deposit in pit shaft, fall into the shaft bottom of oil-water well, after the sand that falls into the oil-water well shaft bottom increased, sand can bury oil-water-layer, the plugging fluid circulation road, make oil-water well be in end-of-life state.In order to recover oil-water well production, the sand that must will fall into shaft bottom is removed clean.The way of removing at present the shaft bottom sand is to adopt liquid stream sand washing method and pump to take out two kinds of methods.Employing liquid stream sand washing method load fluid rushed sand from the oil pipe afterbody, in rear inflow stratum, sand can not return out ground, and the sand that enters stratum can flow out formation influence production again in the oil-water well manufacturing process.Adopt the sand removal of liquid stream sand washing method long in time limit, expense is also high, and it is large that the workman presses labour intensity.At present internal surface of sleeve pipe being had to the pipe cleaning that foreign material are taked is to realize pipe cleaning by the pipeline scraper that is connected to the tubing string bottom, needs separately lower one-trip string, causes flow chart many, and the engineering time is long, and operating cost is high.To the sleeve pipe drifting, be also that next plows the drifting tubing string separately at present, exist equally flow chart many, the engineering time is long, the problem that operating cost is high.
Summary of the invention
The purpose of this utility model is a kind of quick well workover pipe string of design, overcomes the problem that prior art exists, fast and convenient removing shaft bottom sand setting, and carry out simultaneously the pipe cleaning drifting, and reduce flow chart, save operating cost, alleviate labor strength.
The purpose of this utility model is achieved in that and comprises wire rope, sleeve pipe, the sand bucket piston, tapping valve, the sand bucket pump barrel, sand screen, drag for sandpipe, drag for the sand valve, drift size gauge tool, pipeline scraper, nib, the sand post, tapping valve is arranged on the sand bucket piston, the sand bucket piston is arranged in the sand bucket pump barrel, the top of sand bucket piston is connected with the wire rope bottom, the sand bucket pump barrel, drag for sandpipe, drag for the sand valve, drift size gauge tool, pipeline scraper, nib connects successively, sand screen is in the top of dragging for sandpipe, sand screen top is connected with the sand bucket pump barrel, wire rope, the sand bucket piston, tapping valve, the sand bucket pump barrel, sand screen, drag for sandpipe, drag for the sand valve, drift size gauge tool, pipeline scraper, after linking into an integrated entity, nib is lowered on the sand post in sleeve pipe.
The beneficial effects of the utility model are: be lowered to whole instruments with wire rope, equipment removes soon, and can drag for simultaneously sand, pipe cleaning, drifting, therefore, the utility model has overcome the deficiency that prior art exists, workover treatment fast, can reduce flow chart, save operating cost, alleviate labor strength, have significant economic benefit and social benefit.
The accompanying drawing explanation
Accompanying drawing is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model comprises wire rope 1, sleeve pipe 2, sand bucket piston 3, tapping valve 4, sand bucket pump barrel 5, sand screen 6, drag for sandpipe 7, drag for sand valve 8, drift size gauge tool 9, pipeline scraper 1O, nib 11, sand post 12, tapping valve 4 is arranged on sand bucket piston 3, sand bucket piston 3 is arranged in sand bucket pump barrel 5, the top of sand bucket piston 3 is connected with wire rope 1 bottom, sand bucket pump barrel 5, drag for sandpipe 7, drag for sand valve 8, drift size gauge tool 9, pipeline scraper 1O, nib 11 connects successively, sand screen 6 is in the top of dragging for sandpipe 7, sand screen 6 tops are connected with sand bucket pump barrel 5, wire rope 1, sand bucket piston 3, tapping valve 4, sand bucket pump barrel 5, sand screen 6, drag for sandpipe 7, drag for sand valve 8, drift size gauge tool 9, pipeline scraper 1O, after linking into an integrated entity, nib 11 is lowered on the sand post 12 in sleeve pipe 2.
Surface power drive equipment discharges wire rope 1, sand bucket piston 3, tapping valve 4, sand bucket pump barrel 5, sand screen 6, drag for sandpipe 7, drag for sand valve 8, drift size gauge tool 9, pipeline scraper 1O, nib 11 be to descending, foreign material (as dirty piece) when descending on the inwall of the sleeve pipe of scraping on one side 2 carry out drifting on one side, to scrape the foreign material that chip away by sand bucket piston 3, tapping valve 4, sand bucket pump barrel 5, sand screen 6, drag for sandpipe 7, drag for the sand bucket that sand valve 8 forms and pull out, can greatly reduce flow chart, save operating cost, shorten the activity duration.
While dragging for sand, Surface power drive equipment lifts wire rope 1, and wire rope 1 is pumped, liquid from nib 9, drag for sand valve 8, drag for sandpipe 7, tapping valve 4, sand bucket piston 3 drain in sleeve pipe.The sand of extracting out is not blocked and can enter in pump by sand screen 6, the shaft bottom sand setting is pumped down to and drags in sandpipe 7, drags for sandpipe 7 and is tripped out rear sand and dragged for to ground thereupon.
